Abstract
Abstract Apparatus for non-contact, accurate, and continuous determination of the surface temperature on a rotatable part which includes a sensing probe unit containing detecting means for both temperature and distance. The probe unit is constructed such that the distance sensed and the temperature measured are taken at the same point or location on a rotating part. In one preferred embodiment, the temperature sensing element is in direct contact with an electrode for a capacitive excursion measurement system, such that the heat sense is necessarily at the same spacing from the rotor as is the capacitance electrode for measuring the distance from the surface of the rotatable part. Another preferred embodiment utilizes concentrically arranged conductive excursion elements and thermal detector radiation plate. Further, the probe carrying the temperature and distance measuring elements is connected at a housing 1 of the housing around the rotatable part by way of a flange, which has a micrometer screw attached to a slidable member fixed to theprobe for varying the mean or null position of the probe with respect to the path of rotation of the surface of the rotatable member. Other preferred embodiments include further photoelectric speed detecting means arranged concentrically with both the temperature and distance measurement devices so as to also detect the speed at the same location as the temperature and distance.
